Semantik – An Open-Source Mind-Mapping App for KDE

Semantik Presentation Document Creator
Written by Divine

Mindmap diagrams are a productive way to visually organize information using hierarchies and relationship links among pieces of the whole. Today, we have a mind-mapping tool ideal for students, teachers, and creative users and it goes by the name of Semantik.

Semantik (formerly kdissert) is a mind-mapping KDE software for efficiently creating documents including thesis, presentations, and reports.

The created maps are converted into “flat” documents such as reports and presentations via document generators which can be used from both the GUI and Command line. You can edit the maps in linear view (as flat trees) or in 2-D and associate map nodes with text, pictures, tables, or diagrams.

Semantik also features its own internal diagramming tool (semantik-d) and combines all of its features (search function, UML-like widgets, etc.) into a simple and organized GUI.

Semantik was first developed in 2005 and like, Mike, I am surprised that it isn’t more popular. Thanks to Michael Biller for bringing Semantik to my attention.
